BACKGROUND

1. Technical Field

The present disclosure relates to a method for manufacturing a fasteningfor shoes. More particularly, the present disclosure relates to a methodfor manufacturing a braid tip and a braid having the same.

2. Description of Related Art

In general, a braid has braid tips in the two ends, such as the shoelaceand the lace of the boot. The braid tip is usually with a smallercross-sectional area and a greater hardness comparing to other parts ofthe braid, so that the braid can be fixed and is useful for passingthrough the holes.

Thee most common method to manufacture the braid tip is using a plasticor metal cover to surround and fasten the end of the braid so as to getthe braid tip with proper hardness and smaller cross-sectional area.However, the plastic or metal cover is served as additional material forthe braid and always should be handled with cutting, adhesion andfastening process. Hence, using the additional material will produceenvironmental pollution. From the view of users, the braid tip with theplastic or metal cover doesn't take the advantages of non-slip.

Another method to manufacture the braid tip is surrounding the end ofthe braid with acetate sheet and then soaking it into a chemicalsolvent. After melting and forming, the braid tip with harder andsmaller cross-sectional properties is obtained. However, the method alsoapplies the additional material and produces toxic substances duringmelting and forming, which still becomes the environmental issue.

FIG. 2 shows aschematic view of the method for manufacturing the braid tip 231 inFIG. 1. In FIG. 1 and FIG. 2, the method for manufacturing the braid tip231 includes a first weaving step 110 a second weaving step 120 and aheat cutting step 130. In the first weaving step 110, a plurality ofyarns 210 are woven in a loose manner so as to form a braid body 220. Inthe second weaving step 120, the yarns 210 are woven in a tight mannerso as to form a dense braid part 230 connected to the braid body 220,wherein a cross-sectional area of the dense braid part 230 is smallerthan a cross-sectional area of the braid body 220, and the braid body220 and the dense braid part 230 are integrally connected. In the heatcutting step 130, the dense braid part 230 is heat cut so as to form abraid tip 231, wherein the yarns 210 are fixed in a heat cutting end 232of the braid tip 231.

In detail the yarns 210 can be made of the same fiber and dyed with atleast one color or the yams 210 can be made of different fibers and dyedwith at least one color. The yarns 210 can be made of thermoplasticmaterial. Specifically, when the dense braid part 230 is heat cut, theends of the yarns 210 are melted and then solidified, so that the yarns210 can be fixed in the heat cutting end 232 of the braid tip 231.

Moreover, the tight manner means that the yarns 210 are woven in arelative tight way comparing to the loose manner, so that thecross-sectional area of the dense braid part 230 is smaller than thecress-sectional area of the braid body 220, and a hardness of the densebraid part 230 is greater than a hardness of the braid body 220. Becausethe dense braid part 230 is woven to connect to the braid body 220, thebraid body 220 and the dense braid part 230 are integrally connected.Therefore, the braid tip 231 is formed without additional material ofthe plastic or metal cover, and with much less time for heat cutting soas to reduce the toxic emission and be beneficial to our environmentduring the heat cutting step 130.

In the heat cutting step 130, a cutting direction c2 of the heat cuttingstep 130 can be vertical to a length direction b2 of the braid body 220,as shown in FIG. 2. After the heat cutting step 130, the yarns 210 arefixed in the heat cutting end 232 of the braid tip 231, so that a braid200 with the braid tip 231 is obtained.

FIG. 3 shows a flowchart of a method for manufacturing a braid tip 431and another braid tip 433 according to another embodiment of the presentdisclosure. FIG. 4 shows a schematic view of the method formanufacturing the braid tip 431 and the braid tip 433 in FIG. 3.
